Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following embodiments. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.

Non-limiting and non-exclusive examples will be described with reference to fig. 1-3, in which like reference numerals refer to like parts, unless otherwise specified.

The first embodiment is as follows: a spoon sleeve fast packaging bag intermediate product 1 manufactured by bag first and then printed comprises six independent spoon sleeve bag bodies 4, bonding edges 2 of twelve bag bodies are hot-sealing edges bonded by hot pressing, and front fabric and back fabric of the spoon sleeve fast packaging bag intermediate product 1 are 40g of laminating paper and are fabric for post printing. The four-frame bonding edge sealing area 3 is a heat-sealing frame at the edges of the front fabric and the back fabric.

The six independent spoon sleeve bag bodies 4 are formed in such a way that twelve openings of the spoon sleeves are arranged in the common four-frame bonding edge sealing area 3; the inner cavity of the independent spoon sleeve bag body 4 is in a vacuum state. The six independent spoon bag bodies 4 are connected spoon bag bodies 4 which are symmetrically distributed and have vacuum inner cavities.

The first method for manufacturing the spoon sleeve comprises the following steps:

1) a bag maker at the upper end of a supply chain manufactures spoon sleeve fast-manufactured packaging bag intermediate products 1 with different specifications of bag body inner cavities in a vacuum state in batches according to the use categories, and the manufacturing of the inner cavity of a spoon sleeve bag body 4 in the vacuum state comprises the steps of adopting a round pressing roller arranged on bag making equipment to extrude a fast-manufactured packaging bag intermediate product coil stock with an exhaust port at the rear end, and sealing the exhaust port after vacuum is formed;

2) printing pictures and texts on the intermediate product 1 of the fast-manufacturing packaging bag of the spoon sleeve by a single-sheet offset press according to pictures and texts customized by a bag manufacturer at the upper end/lower end of a supply chain;

3) and (3) die-cutting the spoon sleeve fast packaging bag intermediate product 1 after the step (2) into a single spoon sleeve finished product with a non-vacuum state in the bag body inner cavity with the opening being the bag opening as shown in figure 2 by a bag maker at the upper end/lower end of the supply chain.

The spoon sleeve of the embodiment adopts a manufacturing method of firstly manufacturing the spoon sleeve and quickly manufacturing the intermediate product of the packaging bag and then printing, so that the plate making cost is low, the total cost of printing bag making is low, and the bag making speed is high. Because 40g of film-coated paper is easy to roll and the film-coated surface has viscosity, a single piece of film-coated paper is difficult to feed into a color offset press for printing, bag making is performed first and then printing is performed, the film-coated surfaces of the front fabric and the back fabric are pressed relatively, the paper-feeding thickness is increased correspondingly, the film-coated paper rolling can be overcome, the film-coated paper is easy to feed into the color offset press for printing, and the film-coated paper can be prevented from wrinkling easily in the offset printing process and is prevented from being misdetected by a paper-feeding double-sheet detection sensor.

In the embodiment, the manufacturer at the upper end of the supply chain with advanced equipment can manufacture the spoon sleeve fast-manufactured packaging bag intermediate products with different specifications in batches according to the use types, and the manufacturer at the lower end of the supply chain can manufacture the spoon sleeve packaging bags with different specifications in batches or in small batches according to the use types only by printing and die cutting equipment without investing in a bag making machine.

The second embodiment: the intermediate product 5 of the self-standing bag with the convex-concave self-sealing buckle 6 as shown in figure 3 comprises four self-standing bag bodies 7 with the convex-concave self-sealing buckle 6, the four independent bag bodies of the intermediate product 5 of the self-standing bag are symmetrically distributed in two left and right rows, the openings of the bag bodies 7 of the self-standing bag are arranged in two self-standing bag heat sealing areas 10 shared by two self-standing bags consisting of two side heat sealing edges 8 and a bottom heat sealing edge 9 relative to the openings of the two bag bodies, and the bag bodies are in a vacuum state.

The intermediate product 5 of the self-standing bag fast-manufacturing packaging bag enters an ultraviolet curing ink single-sheet offset press for printing in the direction vertical to the bag opening direction, a blanket on a blanket cylinder of the single-sheet offset press is provided with two annular grooves, and when the intermediate product of two rows of conjoined fast-manufacturing packaging bags with opposite bag openings of the convex-concave self-sealing buckles 6 is printed, the two annular grooves correspond to the thickest parts of the convex-concave self-sealing buckles 6 of the two rows of conjoined bag bodies.

The fabrics at the longitudinal central lines of the four conjoined bag bodies of the intermediate product 5 of the self-standing bag quick-manufacturing packaging bag are front fabrics and back fabrics for post-printing, the longitudinal two sides are respectively provided with four layers of fabrics of front and back fabrics and inner-folding bottom fabrics, and the paper-feeding double-sheet detection sensor is right opposite to the longitudinal central line.

The second embodiment has the advantages that: because the distance difference between the convex-concave buttons of the self-supporting bags with different specifications and the bag opening is not large, two annular grooves of the rubber blanket on the blanket cylinder can be suitable for manufacturing middle products of the self-supporting bags with various specifications. The bag body is in a vacuum state, so that the phenomenon that the bag body is broken due to the fact that air is contained in the bag body and is extruded by the printing roller can be avoided.

The foregoing is a more detailed description of the present invention, taken in conjunction with the accompanying drawings, and it is not intended to limit the invention to the specific embodiments described herein. For those skilled in the art, without departing from the spirit of the present invention, several alternatives or modifications can be made to the described embodiments, and all such alternatives or modifications should be considered as falling within the scope of the present invention.
